Each Raid Deck contains a 60 card raid deck, a 30 card event deck, 20 whelp token cards, a 10 Card Treasure Pack and 3 over-sized Onyxia Hero cards. In the charred, desolate Wyrmbog, deep in Dustwallow Marsh, lies the liar of the Black Dragon Onyxia. These limited edition Raid Decks open up the role of an epic foe that only multiple heroes working together can hope to challange. If the heroes win they get the chance to crack open the enclosed Treasure Pack and reap rewards not found anywhere else! The first (and limited) expansion to the Warcraft CCG!
